A battery system refers to the complete assembly of components that work together to store, manage, and deliver electrical energy from rechargeable batteries. It typically includes battery cells, modules, a battery management system (BMS), cooling systems, structural enclosures, and control interfaces. Battery systems are used in a wide range of applications including electric vehicles (EVs), grid-scale energy storage, renewable energy integration, and industrial backup power.
Functionality of a Battery System
Stores energy for later use
Delivers power to drive loads (e.g., motors, buildings, tools)
Balances and protects cells from overcharge, overdischarge, or thermal runaway
Communicates with host systems (e.g., EV controller, grid operator) for performance and diagnostics
